Spoken language can have its impact on the respiratory passage.

Spoken language, due its chronic impact, could be looked upon as one of the factors for its role, either in prevention or causation of respiratory illnesses. There will be variations in articulatory-aerodynamics and respiratory system dynamics among the spoken languages. Geographic variation of disease patterns and uncertain etiologies of some respiratory illnesses, which occur due to insult to the mucosal barrier or the defense mechanism of the respiratory passage, may be explained by the hypothesis of unhealthy language. Habituation to a particular spoken language could mask the symptoms of phonotrauma. Other respiratory illnesses could initiate from the phonotrauma by spoken language. There exist lacunae in the research of languages. Finding out the healthy language could mean relative freedom from respiratory illnesses. Healthy spoken language could relieve the stress on vocal cords and improve the defense mechanism of the respiratory passage.
